Aeglea BioTherapeutics to Present New Data at 2017 ACMG Annual Clinical Genetics Meeting

AUSTIN, Texas, Jan. 17, 2017 -- Aeglea BioTherapeutics, Inc. (NASDAQ:AGLE), a biotechnology company committed to developing enzyme-based therapeutics in the field of amino acid metabolism to treat rare genetic diseases and cancer, today announced that it will present new clinical and research data in two presentations at the 2017 American College of Medical Genetics and Genomics (ACMG) Annual Clinical Genetics Meeting being held at the Phoenix Convention Center from March 21-25, 2017 in Phoenix, Arizona.

Aeglea’s first presentation will include initial data from its Phase 1, open-label study of AEB1102 in two adult patients with Arginase I deficiency. The results show that AEB1102 was well tolerated and effective at reducing arginine levels in the blood of both patients. Treatment with AEB1102 resulted in a dose-proportional decrease in plasma arginine levels of between 25 and 49 percent of pre-dose levels one week after dosing.

The company’s second presentation includes research data on newborn screening protocols. The research data demonstrated that Arginase I deficiency can be screened with very high efficiency, which underscores the company’s belief that it is a potential candidate for future addition to the Recommended Uniform Screening Panel (RUSP).

Full abstracts are available online at www.acmgmeeting.net. Details of each of the two poster presentations are listed below.

About Aeglea BioTherapeutics
Aeglea is a biotechnology company committed to developing enzyme-based therapeutics in the field of amino acid metabolism to treat rare genetic diseases and cancer. The company’s engineered human enzymes are designed to modulate the extremes of amino acid metabolism in the blood to reduce toxic levels of amino acids in inborn errors of metabolism or target tumor metabolism for cancer treatment. AEB1102, Aeglea’s lead product candidate, is currently being studied in two ongoing Phase 1 clinical trials in patients with advanced solid tumors and acute myeloid leukemia/myelodysplastic syndrome (AML/MDS). Additionally, Aeglea is recruiting patients into its ongoing Phase 1/2 trial of AEB1102 for the treatment of patients with Arginase I deficiency. The company is building a pipeline of additional product candidates targeting key amino acids, including AEB4104, which degrades homocystine, a target for an inborn error of metabolism, as well as two potential treatments for cancer, AEB3103, which degrades cysteine/cystine, and AEB2109, which degrades methionine.
